Features
- TapAction™ AUTOCUT® Cutting Head -
  TapAction™ allows users to adjust the line length simply by tapping the cutting head against the ground.
- IntelliCarb™ Compensating Carburetor -
  The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.
- Loop Handle (R) -
  Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited.
- Anti-Vibration System -
  STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
- Multi-Function Control Handle -
  Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle.
- Simplified Starting Procedure -
  To get started, users simply pump the fuel primer, set the choke, and pull the starter cord. The built-in stop switch allows the user to turn off the engine with a simple press of the button. When the engine is off, the throttle lock automatically returns to the "start" setting. The tool will be ready to start again when the user is ready to get back to work.
- Air Filter Cover -
  Easily remove the cover for fast and easy filter cleaning or replacement.
- Protected or Enclosed Control Cables -
  Dangling and loose wires are eliminated.
- Protected Spark Arrestor Muffler -
  Large baffles reduce noise level and contain a screen designed to reduce the emission of sparks.
- Protected Spark Plug -
  The spark plug is protected yet easy to change.
- Protected Choke Lever/Knob -
  The choke is protected to help prevent damage.
- High-Tech Polymer Housing -
  Housings are lightweight, withstand greater impact, and are corrosion-resistant.
- Heavy-Duty Steel-On-Steel Clutch -
  Centrifugal clutch is designed to reduce slippage.
- Purge Pump Primer -
  By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses.
- Upright Translucent Fuel Tank -
  Easily check the fuel level before starting work. If fuel is needed, the upright position makes the tank easier to fill.
- Fully-Lined Drive Shaft -
  A lined shaft provides smooth operation and less vibration.
- Throttle Trigger Interlock -
  This safety feature must be depressed before the trigger can be activated.
- Made in America -
  A majority of STIHL products sold in America are made in America of U.S. and global materials.
